3-aryl-4-hydroxy-delta3-dihydrofuranone derivatives

ABSTRACT

The present invention relates to a new 3-aryl-4-hydroxy-Δ 3  -dihydrofuranone derivatives of the general formula (I) ##STR1## in which the radicals A, B, G, X, Y, Z and n have the meaning given in the description, to a plurality of processes for their preparation, and to their use as pesticides.

The present invention relates to new 3-aryl-4-hydroxy-Δ³ -dihydrofuranone derivatives, to processes for their preparation and to their use as pesticides.

It has been disclosed that certain substituted Δ³ -di-hydrofuran-2-one derivatives have herbicidal properties (cf. DE-A 4,014,420). DE-A 4,014,420 also describes the synthesis of the tetronic acid derivatives used as starting compounds (such as, for example, 3-(2-methylphenyl)-4-hydroxy-5-(4-fluorophenyl)-Δ³ -dihydrofuran-2-one). Compounds which have a similar structure are known from the publication Campbell et al., J. Chem. Soc., Perkin Trans. 1 1985, (8) 1567-76, but no insecticidal and/or acaricidal activity is indicated. Furthermore, EP 528,156 discloses 3-aryl-Δ³ -dihydrofuranone derivatives having herbicidal, acaricidal and insecticidal properties, but the activity described therein is not always sufficient.

After the specified periods of time, the destruction in % is determined. 100% means that all the caterpillars have been killed; 0% means that none of the caterpillars have been killed.

In this test, for example the compounds of Preparation Examples Ib-6, Ib-8, Ic-4 and Ic-5 resulted in a destruction of 100% after 7 days at an exemplary concentration of active compound of 0.1%, while the compounds of the prior art resulted in a destruction of not more than 40%.

EXAMPLE B

Myzus test

Solvent: 7 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Cabbage leaves (Brassica oleracea) which are heavily infested with the green peach aphid (Myzus persicae) are treated by being dipped into the preparation of active compound of the desired concentration.

After the specified periods of time, the destruction in % is determined. 100% means that all the aphids have been killed; 0% means that none of the aphids have been killed.

In this test, for example the compounds of Preparation Examples Ic-4 and Ic-5 show a degree of destruction of not less than 85% after 6 days at an exemplary concentration of active compound of 0.01%.

EXAMPLE C

Critical concentration test/root-systemic action

Test insect: Phaedon cochleariae larvae

Solvent: 4 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

The preparation of active compound is intimately mixed with soil. The concentration of the active compound in the preparation is of practically no importance, only the amount by weight of active compound per unit volume of soil, which is given in ppm (=mg/l), being decisive. The treated soil is transferred into pots and these are planted with cabbage (Brassica oleracea). The active compound can in this way be taken up from the soil by the roots of the plants and be transported into the leaves.

To demonstrate the root-systemic effect, the leaves are infested with the abovementioned test animals after 7 days. After a further 2 days, the evaluation is made by counting or estimating the dead animals. The root-systemic action of the active compound is deduced from the mortality figures. It is 100% if all test animals have been killed and 0% if just as many test insects are still alive as in the case of the untreated control.

In this test, for example the compound of Preparation Example Ic-4 shows a degree of destruction of 100% at an exemplary concentration of active compound of 20 ppm.

EXAMPLE D

Tetranychus test (OP resistant)

Solvent: 3 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.

Bean plants (Phaseolus vulgaris) which are heavily infested with all development stages of the two-spotted spider mite (Tetranychus urticae) are sprayed with a preparation of active compound of the desired concentration.

After the specified periods of time, the destruction in % is estimated. 100% means that all the spider mites have been killed; 0% means that none of the spider mites have been killed.

In this test, for example the compound of Preparation Example Ic-5 showed a degree of destruction of 100% after 14 days at an exemplary concentration of active substance of 0.004%.

EXAMPLE E

Panonychus test

Solvent: 3 parts by weight of dimethylformamide

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, and the concentrate is diluted with emulsifier-containing water to the desired concentration.

Plum trees (Prunus domestica) approximately 30 cm in height, which are heavily infested with all development stages of the red spider (Panonychus ulmi), are sprayed with a preparation of active compound of the desired concentration.

After the specified periods of time, the activity in % is determined. 100% means that all the spider mites have been killed; 0% means that none of the spider mites have been killed.

In this test, for example the compound of Preparation Example Ic-4 showed a degree of destruction of 100% after 14 days at an exemplary concentration of active substance of 0.004%.

EXAMPLE F

Pre-emergence test

Solvent: 5 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of the active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control.

The figures denote:

0%=no action (like untreated control)

100%=total destruction

A clearly superior activity and crop plant selectivity compared with the prior art are shown, in this test, for example by the compounds of Preparation Examples Ia-4, Ib-6, Ib-8, Ic-4 and Ic-5.

EXAMPLE G

Post-emergence test

Solvent: 5 parts by weight of acetone

Emulsifier: 1 part by weight of alkylaryl polyglycol ether

To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.

Test plants which have a height of 5-15 cm are sprayed with the preparation of the active compound in such a way as to apply the particular amounts of active compound desired per unit area. The concentration of the spray liquor is chosen so that the particular amounts of active compound desired are applied in 2,000 l of water/ha. After three weeks, the degree of damage to the plants is rated in % damage in comparison to the development of the untreated control. The figures denote:

0%=no action (like untreated control)

100%=total destruction

A clearly superior activity and crop plant selectivity compared with the prior art are shown, in this test, for example by the compounds of Preparation Examples Ia-4, Ib-6, Ib-8 and Ic-4.

EXAMPLE Ib-1 ##STR382##

3.25 g (10 mmol) of the compound Ia-1 are introduced into 40 ml of absolute methylene chloride, 1.42 g (14 mmol) of triethylamine and a spatula-tip of DMAP were added, a solution of 0.94 g (12 mmol) of acetyl chloride in 20 ml of methylene chloride was added dropwise, and the mixture was stirred for 16 hours at room temperature.

For working-up, the reaction mixture is washed using aqueous citric acid, NaHCO₃ solution and NaCl solution, dried and evaporated in a rotary evaporator. Further purification is carried out by flash chromatography on silica gel using cyclohexane/ethyl acetate 3:1.

Yield: 1.70 g (46% of theory) of a solid of m.p. 126° C.
